Five races of the Eurasian silver-studded blue butterfly, Plebejus argus, are restricted to different habitats in north Wales and north-west England. One of these races is extinct, and others are threatened. The four extant forms differ in morphology, habitat, host plant choice, performance on different host plant species and species of associated ant. Some of these differences are maintained in captivity, suggesting evolutionary divergence. Different races with different habitat requirements… Expand

Figures and Tables from this paper

Divergent patterns in the mitochondrial and nuclear diversity of the specialized butterfly Plebejus argus (Lepidoptera: Lycaenidae)
TLDR
The hypothesis that females are philopatric is consistent with direct observations of the restricted colonization abilities of the butterfly, while the relatively homogeneous genetic structure revealed by previous allozyme studies in some areas might be explained by the possible higher mobility of males. Expand
Phylogenetic relationships in brown argus butterflies (Lepidoptera: Lycaenidae: Aricia) from north-western Europe
TLDR
Investigation of phylogenetic relationships and phylogeographic patterns in this species group using mitochondrial and nuclear markers in comparison with morphological variation shows that the sample is composed of two closely related species, A. agestis and A. artaxerxes. Expand
Evidence based conservation of butterflies
TLDR
Within-patch larval habitat quality is again critical at the meta-population scale, explaining slightly more examples of patch occupancy than site isolation, and the higher density populations supported by optimum habitat are less likely to go extinct, and immigrants to new high-quality patches have a higher probability of founding new populations. Expand
Taxonomy and conservation of allopatric moth populations: a revisionary study of the Notoreas perornata Walker complex (Lepidoptera: Geometridae: Larentiinae), with special reference to southern New Zealand
TLDR
It is argued for an inclusive approach to conservation of all populations belonging to the Notoreas perornata Walker complex, and suggested priorities (based on current distribution and threats) are listed. Expand
METAPOPULATIONS OF FOUR LEPIDOPTERAN HERBIVORES ON A SINGLE HOST PLANT, LOTUS CORNICULATUS
TLDR
The results do not support the idea that patchiness promotes regional coexistence through multispecies metapopulation dynamics, and suggest that conservation recommendations must be based on detailed analysis of the requirements of each key species in order to understand their spatial dynamics. Expand
Considering Local Adaptation in Issues of Lepidopteran Conservation—a Review and Recommendations
TLDR
The importance of considering local adaptation in butterfly conservation is addressed and investigations of regional specialization that may enhance the effectiveness of conservation strategies such as captive rearing, habitat restoration and the introduction of populations into new localities are encouraged. Expand
Host compatibility as a critical factor in management unit recognition: population‐level differences in mussel–fish relationships
TLDR
It is demonstrated that small-scale cross-compatibility testing can be effectively used to diagnose the sources of variability in host relationships with direct management implications, and can enhance the targeting of management actions in many biological applications addressing species conservation, biological invasions and ecosystem processes. Expand
The importance of unique populations for conservation: the case of the great orme’s head grayling butterfly Hipparchia semele (Linnaeus, 1758) (Lepidoptera: Satyrinae)
Small populations with unusual characteristics subject to extreme conditions provide opportunities for exploring adaptability in the face of environmental changes. Two sets of data have been examinedExpand
A new method to identify important conservation areas applied to the butterflies of the Aegean Islands (Greece)
TLDR
The new method is applied here to the butterflies of the Aegean Islands (Greece) using different (national and international) red lists and results were consistent with both classifications based on multivariate analyses and findings from other researches. Expand
LARGE‐SCALE PATTERNS OF DISTRIBUTION AND PERSISTENCE AT THE RANGE MARGINS OF A BUTTERFLY
One major goal of conservation biology in fragmented landscapes is to identify the attributes of habitat networks that influence metapopulation persistence, and thereby to determine whetherExpand

The status and conservation of the butterfly Plebejus argus L. (Lepidoptera: Lycaenidae) in North West Britain
TLDR
The decline of P. argus appears to be a compound effect of reduced amounts of suitable habitat and inability to colonise them: the distances are often too great, and active conservation is required. Expand
Genetic Analysis of Founder Bottlenecks in the Rare British Butterfly Plebejus argus
TLDR
Significant reductions in the numbers of rare allozyme alleles were found in descendent populations, presumably as a result of drift during colonization bottlenecks, and there was no evidence for any increase in fluctuating asymmetry among descendedent populations. Expand
Intraspecific variation in habitat availability among ectothermic animals near their climatic limits and their centres of range
TLDR
The model predicts that an increase of 2–3 °C can result in a large increase in the area of habitat available to these north temperate species, that the length of time that individual patches of successional habitat may be occupied increases and that the distance between habitat patches within the biotope decreases. Expand
Spatial dynamics of a patchily distributed butterfly species
TLDR
The regional distribution was constrained by the inability of the butterfly to colonize suitable habitat that was further than a fex kilometres from existing metapopulation; some of these sites are now populated by P.argus following successful introductions. Expand
Evolutionary consequences of habitat fragmentation in a localized butterfly
TLDR
Significant family effects for total mass, relative thoraxmass, relative abdomen mass and (for females only) relative wing area indicate that these traits may have a heritable component, and therefore have the potential to respond to selection acting on flight ability. Expand
Molecular population structure and the biogeographic history of a regional fauna : a case history with lessons for conservation biology
TLDR
These concordant phylogeographic patterns among independently evolving species provide evidence of similar vicariant histories of population separation, and can be related tentatively to episodic changes in environmental conditions during the Pleistocene. Expand
Three ways of assessing metapopulation structure in the butterfly Plebejus argus
TLDR
Migration and dispersal ability, colonization of newly created habitat, and genetic differentiation of local populations within a metapopulation was investigated in the butterfly Plebejus argus. Expand
Population diversity: its extent and extinction.
TLDR
This work estimates the number of populations per area of a sample of species from literature on population differentiation and the average range area of an species from a samples of distribution maps, which yields an estimate of about 220 populations per species. Expand
Specializations and polyphagy of Plebejus argus (Lepidoptera: Lycaenidae) in North Wales
Abstract. 1. The polyphagous butterfly, Plebejus argus L., was found to have specialized requirements: eggs are laid along vegetation/bare ground margins, larvae specialize on tender meristematic andExpand
What to protect?—Systematics and the agony of choice
TLDR
It is concluded that two basic rounds of analysis are required: recognition of global priority areas by taxic diversity techniques; and, within any such area, analysis without taxic weighting to identify a network of reserves to contain all local taxa and ecosystems. Expand
